Prediction of Density of Chromium Steels by Using the Relation Obtained from Sessile Drop Method and Thermodynamic Phase Calculation Data

Abstract

The change in the density of chromium steels with phase at a temperature range from 1 000 to 1 973 K have been studied by a sessile drop profile method. Measurement of the density by a sessile drop profile method has to be carried out under heating conditions to avoid the influence of both undercooling and the shrinkage within the sample during solidification. The density of chromium steels were dependent on the phase but not chromium contents. The density in the liquid, δ and γ single phase, (liquid+δ), (liquid+γ), (δ+γ) coexisting states and (liquid+δ+γ) coexisting state could be predicted using the experimental results.
